"We're asking the Government to really consider all forms of ground transport, be that better bus services, be it a train link, be it widening the roads to allow more cars to enter the airport," he said.

"Hopefully by the end of the calendar year the Government will be in a position to start making some announcements."

Avalon concerns

The chief executive of Avalon Airport, Justin Giddings, says the Government should be focusing on developing Avalon rather than Melbourne Airport.

He says it would be cheaper to build a rail link to Avalon.

"It's about $150 million, compared to billions to put a new rail [line] into Tullamarine," he told ABC local radio.

"We've got plans for new runways as well, but they don't go over residential areas.

"All the new runway's going to do at Tullamarine is just put pressure on their non-curfew status eventually and really it's just going to add massive traffic congestion that they've already got."
